Low duty-cycle pulse testing is used to maintain junction temperature as close to ambient temperature as possible.
In the non-Darlington configuration, if the output switch is driven into hard saturation at low switch currents ( ≤ 300 mA) and high driver
currents ( ≥ 30 mA), it may take up to 2 μ s for the switch to come out of saturation. This condition effectively shortens the off time at
frequencies ≥ 30 kHz, becoming magnified as temperature increases. The following output drive condition is recommended in the
non-Darlington configuration:
Forced β of output switch = I C,SW / (I C,driver – 7 mA) ≥ 10, where ～ 7 mA is required by the 100- ? resistor in the emitter of the driver to
forward bias the V be of the switch.
